.T 0 all whom, it may concern:

Be it known that I, DUDLEY S. SEYMOUR, a citizen of the United States, residing at Oak Park, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Power-Transmitting Devices, of which the following is a description, referencebeing had to the accompanying drawings, and to the letters and figures of reference marked thereon.

My invention relates to new and useful improvements in power transmitting devices, and while said. power transmittin device may be used for various purposes, t e samev is more especially adapted for use in connection with sewing machines where power is transmitted from a power shaft through the transmitter to the stitching mechanism.

The principal object of my invention is to provide a means for supporting said Ipower transmitter, whereby the same may e adjusted relative to the parts from which power is received and to which power is delivered.

The invention consists in the novel construction and arrangementof parts hereinafter shown and particularly pointed out in the appended claims.

One embodiment of my invention is illusstrated in the accompanying drawings, in which:--

Figure 1 is a side elevation of my improved supporting device for a power transmitter. Fig. 2 is an end elevation of the same. F 1g. 3 1s a sectional view showlng the spring for holding the parts separated.

The power transmitter is mounted on a supporting frame 1 which may be held by any convenient means such bolts to the under side of the bench or table u on which the machine to be operated is 'p aced. Said frame has depending from its opposite ends bearings 2, 3 through which loosely asses a sha t4. .Secured t0 the shaft 4 1s a bracket 5. In the resent embodiment of my invention, I ave shown said bracket as having ears 6 and 7 spaced so as to fit between the bearings 2 and 3 and said ears are secured to the shaft 4 by means of screws 8 and 9.' The lower end of my bracket 5'is provided with a split bearing 10,

which surrounds the supporting shaft ]1 of my transmitter, said split bearing being secured to the shaft 11 by a screw 12. Loosely as screws 'or mounted u on the shaft 11 is a belt wheel 13, said belt W reel being held on the shaft by the thrust bearing 14. The pulleys 15 are also loosely mounted on the shaft 11, and are held out of contact with the belt Wheel 13 by the usual spring, 23, which is mounted upon projecting flanges extending from the pulley 15 and belt wheel 13 in the usual manner as shown in Fi 3. 'The belt wheel 13 is provided with the usual brake disk 16. A lever 17 is pivoted on the bracket 5, and carries a brake shoe 18 of the ordinary construction, co-operating with the brake disk 16. The lever 17 is also provided with an arm 19, which operates to shift the pulleys into clutching engagement with the belt wheel 13. The bracket 5 is provided with oppositely extending arms 20, each of which is screwthreaded for the reception of a screw 21. The supporting frame 1 is provided with hearing lugs 22, 22, with which said screws 21 co-operate. The bracket 5 has cutwardly extending flanges-5, which serve to strengthen the bracket, and said flange is slotted to form a passage for the lever 17. This arrangement of parts brings the stress caused by operating the lever directly underneath the support for the bracket. I When it is desired to adjust the position of my power transmitter relative to the power shaft from which power is received or the mechanism to which power is delivered, one of said screws 21 is withdrawn from its supporting arm and the other screw is turned so the transmitter about the shaft 1 as an axis, until the first named screw is again drawn into contact with its co-o crating lug 22.

Itwill-be apparent tl screws 21 one way or the other, the bracket may be swung either to the right or to the left, as viewed in Fig. 2, and that said bracket may be clamped securely in its adjusted position by the means for adjusting the same.

' By mounting the lever 17 on the bracket, it will be noted that all adjustments of the bracket carry with it the lever and its co-operating parts, so that the said parts remain in proper relation to each other regardless of the osition of the bracket, and I have, thereorc, provided a means whereby the same relative position of the ulley, belt wheel, shaft, the pullcy-shil' ting means and' the a as to swing the entire supporting bracket for rat by turningthe brake means, is maintained for all adjust-- the-bracket angularly the same may be adjusted in any other manner, without departing from the spirit of my invention, so long as the adjustment is substantially at right angles to the axes of the pulley and belt wheel.

Having thus articularly described my invention, what folaim as new and desire to secure by Letters Patent is z 1.
